Abstract

The efficiency of photon-echo processes typically lies in the 0.1–1%
range. For many photon-echo-based applications suggested in optical storage
and all-optical communication the photon-echo output pulses would need to
be used as input data to a new photon-echo process. In such cases amplification
of the photon-echo output signals would be necessary for an acceptable signal-to-noise
ratio to be obtained. We show that a Pr-doped ZBLAN fiber is able to produce
significant amplification of photon-echo signals generated in Pr-doped Y2SiO5 at 606 nm.
